'To all whom it may concern:

Be it known that I, ALBERT NUNAMAKER,

a citizen of the United States, residing at Cleveland, in the county of Cuyahoga and 5 State of Ohio, have invented new and useful Improvements in Motor-Vehicles, of which the following is a specification.

This invention relates to motor-vehicles,

' and particularly to that class in which the front or steeringwheels are connected to the driving mechanism, so that four-wheeltration is permitted, making all the wheels driving-wheels.

The invention resides in the particular construction of the connections between the wheel and the driving-axle .at the steering joint or knuckle. 7 An embodiment of the invention is shown in the accompanying drawings, in which- Figure 1 is a central vertical section. Fig. 2 is a top plan view ofthe knuckle-joint. Fig. 3 is a section on the line 3 3 of Fig. 1. Fig. 4 isa section on the line '4 4 of Fig. 1. Figs. 5' and 6 are details of a roller bearin sliding connection between the universa jointand the driving-axle. Fig. 7 is a longitudinal section of a modification.

Referring specifically to the drawings, C

indicates a universal joint of known con-.

struction connecting the driving-axle J with the spindle J of the Wheel. The wheel-hub is indicated at L, and it is fast upon the spin-. dle-that is, the hub turnswith the spindle. R indicates spokes. The axle tube or casing I has mounted rigidly thereon the inner steering-yoke D, the arms of which are connected to the arms of pins P, provided with nuts Q. This forms a the outer steering-yoke K by means of pivotknuckle-joint, between the shaft-casing and yoke D and the yoke K, permitting the latter to turn to steer the vehicle. The yoke K has an arm K, to which the steering-gear is connected.

Upon the outer end of the shaft-section J is sleeved and fixed a ring-cone G, opposite which is a ring-cup F, seated in the yoke D, the on and cone forming a raceway for the balls the whole forming bearings upon which .the outer end of the axle J turns.-

The inner end of the axle-spindle J projects as a stub through the outer steeringoke K and is su ported by ball-bearings F between cones on the stub of the spin die and ring-cups F, let into the outer yoke -K. These parts form the bearings and supports for the wheel, which, as said, rotates with the spindle J.

The universal joint C has two projecting necks N, arranged at right angles to'each other, and the ends of the axle J and spindle J are slotted lengthwise to receive the outer ends of these necks, the necks beingsquared so that the motion is transmitted irorn the axle J through the universal joint to the spindle J. center with the pivots P, and to accommo date the end play, which is bound to occur to a greater or less extent in consequence of vibration or looseness oi the parts, the inner neck N is provided with a plurality of rollers n, set upon pins in recesses in the upper and lower edges of the necks and arranged to bear against the opposite walls of the longitudinal slot in the end of the axle J. This allows an end play without friction and pre vents any distortion or undue wear on the universal joint.

The hub L and outer cup G are preferably splined onto the spindle J,, as indicated at 0, and the outer end of the axle is provided with an adjusting-nut O, bywhich wear at the bearings E can be taken up by sliding the hub and bearing-cone inwardly to the necessary extent. The ring G backs against the hub. The adjusting-nut is covered by the huh-cap M. v

In the modification shown in Fig. 7 a different manner of mounting the wheel and itss indle is shown. Referring particularly to t lie, the outer yoke member K is continued as a sleeve 7c over'theaxlespindle J' which rotates in the sleeve upon hearings it at the inner end thereof. The wheel-hub it is mounted upon bearings L on the outside oi the sleeve is and is clutched to and driven with the spindle by means of a clutch-piece O, which consists of an annular member titted upon the squared end of the spindle J andheld thereon by a cottero and having a notched rim at 0', which engages corresponding notches in the outer rim or edge of the hub L. A cap M is screwed onto the hub and covers the end of the spindle. The bear ings L are formed by cones on the sleeve and cups which abut against ribs E on the The universal joint is set on a,

inside of the hub, with balls between the cups and cones. The outer cone is threaded onto "the sleeve to adjust the bearings.

What I claim as new, and desire to secure by Letters Patent, is-

c 1. The combination, in a mechanism of a :"p maul the class stetei'of an axle and a Wheel-spin.-

die heving non-circular recesses in their ends,

and e inliversel joint between the same new connecting-necks fitting in said recesses and having longitudinal movement therein. 2 'Ehe eo mhnietion, in a mechanism of the stated, of an axle and e wheel-spindle having non-circular recesses in their ends, and ii nniverssl joint having eonneetingmeeks fitting in said recesses and having lengthwise movement; ierein, end rollers between said necks and he walls of the recesses 3. in at mechanism of the kind described, combination, an axle, a. wlwehspindle having it universal joint therewith, a casing over the axle, a yoke pivotally connected to the eesing and having a sleeve over the spindle, hearings between the spindle and the sleeve, beerings'ings at both the inner and outer ends ()1 the sleeve, upon the outside thereof,

scenes the ring at the outer end being screwed on the sleeve for adjustment, and a wheel-hub mounted u on said bearings and connected to the spin le. I

4. Thecombinstion with a motonvehiele sxle-eesing having at the outer end a pivoted steering member, of a spindle, a wheel mounted thereon'to turn therewith, beerin rings and rollers between thespindle and said members. one'of which rings backs against the inner end of the Wheel-hub, and an adjusting nnt screwed on the end of the spindle against the outer end of the hub.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
